Mechanical properties

Sefar filter belts are made from carefully selected polymers such as PP, PET, PVDF and PEEK. The right choice of polymer helps to ensure the appropriate chemical resistance for each specific filter belt application.

Belts from Sefar are designed to maintain their performance during their entire life and ensure troublefree operation. The appropriate selection of material is crucial to ensure performance under high temperatures.

Sefar belts are designed to cope with heavy loads, quick rotating and extra large rotary drum filter units. Sefar fabrics are specially optimized for high strength, the best tracking stability and the longest possible belt life.

Suspension properties

The offered pore size selection ranges from 5 µm to over 150 µm for the processing of various suspensions. Depending on the slurry properties, Sefar offers a suitable filter solution to meet your requirements concerning particle retention and filtrate clarity.

Filtration capacity

Drum filter belts from Sefar have a maximized number of pores and optimized permeability to guarantee the expected throughput. Special needs concerning cake dryness or high filtration efficiency can be met by using the latest Sefar filter media developments.

Filter media technology

Sefar double-layer weave technology is the unique filter media construction combining two different fabric layers mechanically through weaving. In comparison to a single-layer fabric, belts made from SEFAR TETEX DLW deliver outstanding filtration results: high vertical and lateral liquid flow properties, excellent resistance against creasing and mechanical stress. Best filtration results and enhanced lifetime is achieved by combining the functions of a fine filtration layer and a support drainage layer.
